Fluid Bed Processor - GEA Pharma Systems

Optimized DesignsProcess filtersIn granulation, drying, and most pelletizingapplications, a process filter is used to trapQuick closingvalvePolice filtersSuction fanSilencermall particles, which are returned to the bedwhen the filter is cleaned. In coatingapplications, fine particles usually need to beremoved. Fluid beds that are used for morethan one type of process can be suppliedwith interchangeable process filters.11 Single shaker bag filterA simple, basic filter with a single bag,which is cleaned by shaking. Fluidizationstops during filter cleaning.2 Multi shaker bag filter2This filter is divided into two or moresections, with a separate filter bag in eachPre-filterPre-heaterone. Bags are cleaned individually byshaking the filter, while fluidizationcontinues in the other sections, for fasterand more efficient production.Humidifier3 Blow-back filterThere are multiple filter bag sections in thisdesign. Cleaning takes place one bag at atime, so that a large proportion of the filteris always available for continuousfluidization.34 Cartridge filterStainless steel filter cartridges are cleanedFilterHeater (faceand by-pass)Cooler/condenserone at a time, so that a large proportion ofthe filter is always available for continuousfluidization. Unlike bag filters, this systemcan be cleaned-in-place.45 Particle retainerUsed for coating applications, this designretains the coarser particles and returnsthem to the process, removing the dust to anexternal filter unit.57
